A grain of Silver is a very small amount of the metal. There is 15.43 grains in a gram. So a typical 5 grain bar is a little more than 3 grams of Silver. 500 grains or 500gr is the equivalent of 1.04 troy ounces of Silver. There are 480 grains per troy ounce (31.1g).

Silver grains are also known as Silver shot. They are little balls of Silver typically about 6mm across that are made from various grades and purity of Silver, each ball weighing exactly one grain or 64.79891mg. They are favoured by Jewellers and such like because it is much easier to take a few grains to make a piece of jewelry rather than have to break down a bar. Typically you would buy a troy ounce of grains.
The term 'grain' is believed to have come from the Bronze age where the weight of wheat and barley grains where used to determine mass. A barley grain for example weighs 65mg, which is pretty accurate to the more exacting, modern day figure. As previously mentioned one grain of Silver, Gold or any precious metal weighs exactly 64.798.81 milligrammes.
There are lots of other theories as to the name 'grain' or its use as a means of measurement. However, the Barley grain theory is largely regarded as the most likely means of explanation.
Grains and grams also have a very similar abbreviations too – not to be mixed up when you are buying Silver! Grams being signified by a (g), grains being identified by a (gr) like so.
Abbreviation or prefix, unit symbol, for gram is: g

Oh, one final thought on grains of Silver. It's very hard to stack 'BB' shaped grains too - leave them for the industrialists and manufacturers! ;-)
